gaganggoyal/indiaoffers ? reverse-engineered prompt

Build me an SEO friendly Indian deals site called IndiaOffers.in that shows shoppers the real final price of a deal, not just the headline discount.

I want each deal page to calculate the best effective price by combining the product discount, any bank or card offer, and coupon codes, then show the best way to pay in a simple ranked widget. The site should be server rendered, fast, and work with clean shareable URLs for deals and landing pages. It should also have special search pages like loot deals, ₹1 deals, free deals, under 99 deals, flash deals, cashback deals, and coupons, with the right items automatically showing up based on the deal data.

Please include user accounts with email OTP login, a public deal submission flow, click tracking for outbound merchant links, and an admin area where I can manage deals, offers, coupons, stores, banners, and users. Make it easy to run locally with seed data, and if you need current docs for anything, look them up online.
